MOUNTING 'FOR RIF'LE-TELESCOPES.

sPEciF'rcA rIo'N forming part of Letters Patent No. 740,327, datedSeptember 29, 1903.

Application filed February 6, 1902- Serial No. 92,944. (No model.)

To all whom it may concern:

Be it known that I, CHARLES EDWIN STALL- 001?, a citizen of the'UnitedStates, residing at Sac City, in the county of Sac and State of Iowa,have invented certain new and useful Imp'rovements'in TelescopicMountings for Rifles, of which thefollowing is a specification.

My invention relates to improvements in mountings for telescopes appliedto rifles, and particularly in mountings of that class which permitvertical or lateral adjustment of the telescope, or both, as conditionsmay require.

In my invention the mountings proper or holders for the telescope areprovided'with springs which bear upon the telescope to press it bothdownward and laterally, and I employ in connection with such mountings agraduated slide which is'practically wedgeshaped and provided on itsinclined edge with an elongated open slot or notch whose shoulders areadapted to engage the mountings, as hereinafter described. By adjustingthe slide longitudinally in the mountings the telescope may be 1ifted orpressed laterally and held in the position to which it is adjusted.

The details of construction, arrangement,

and operation of parts are as hereinafter deof different forms of thewedge-shaped slide.

Fig. 8 is a cross-section on the line 8 8 of Fig. l.

As shown in Fig. l, a telescope B is held in mountings A and A appliedto a rifle-barrel 0. As shown in said figure, a spring fprojects fromeach of the mountings A and A and bears downward upon the telescope B,and wedge-shaped slides Wand k are applied as required for adjusting thetelescope vertically and laterally, respectively.

I will now describe the details of construction and arrangement ofparts.

' As shown in Figs. 2, 3, and 4, the several mountings A, A and A arepractically rings or short tubes provided with shanks b, by which theyare secured to the rifle-barrel O in Fig. l as the rear mounting and theform A as the front mounting for the telescope B. The form A is providedwith a notch c in its lower side toreceive a wedge-slide, as shown inFigs. 1 and 8. A lateral clamp-screw dis applied to the right-hand sideof the mounting A and when duly adjusted the telescope B will be heldsecurely between the several bearings provided by the springs e and f,the screw it, and the wedge ]L2. The form of mounting A in which thefront end of the telescope B is held differs from the form A in that thenotch or slot 0 for the wedge-slide is arranged laterally or atone side,and ascrew 1c is applied at the bottom of the mounting A for the purposeof clamping the wed ge-slide inserted at that point. In Fig. 1 the formh of the wedge-slide there applied for lateral adjustment of thetelescope B is that shown in Fig. 7. It will be seen by inspection ofFigs. 5, 6, and 7 that each of the forms of wedge-slide shown isstraight on one side edge and inclined on the other and also providedwith an elongated slot or notch having square end shoulders t'j. Theportion of the slide included between t and j may be curved, as

shown in Fig. 5, or straight, as shown in Fig.

6, or straight and notched, as shown in Fig. 7. In Figs..5 and 6 theslide is shown graduated in the manner of an ordinary foot-rule, and inFig. 7 the severalnotches formed in the cut-out or slotted portion areindicated by numerals which are equivalent to the graduations. When thewedge-slide is applied as shown in Fig. 1, the shoulders z'j limit itsslides in any position to which they may be desired. When the form It(shown in Fig. 7)

is employed, as indicated in Fig. 1, its notches will engage theclamp-screw d. It will be apparent that pressure of the springs e f isopposed to that exerted or applied to the wedgeshaped slides, and thusthe telescope B is at all times held with due security.

Practically the slides are adapted to be interchanged, and they will bemade of different sizes or lengths and with any preferred graduation toadapt them for use with different telescopic mountings.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with a telescope and holders therefor, having guideslots and springs arranged as described, of a Wedgeshaped slide adaptedfor insertion and adjustment in the slots, and means for clamping it inany adjustment, substantially as shown and described.

2. The combination, with a telescope and mountings therefor havingsprings and slots substantially as described, of a wedge-shaped slideprovided in its inclined'sidewith an elon gated notch having endshoulders adapted to engage the mounting as specified.

3. The combination, with a telescopic mounting, and a telescope heldtherein, of springs applied to said mountings, wedgeshaped slidesarranged opposite the springs, and screws arranged for clamping theslides in any adjustment, substantially as shown and described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES EDWIN STALLCOP.
